What is Namenda XR?
Memantine is used to treat moderate to severe confusion (dementia) related to Alzheimer’s disease. It does not cure Alzheimer’s disease, but it may improve memory, awareness, and the ability to perform daily functions. This medication works by blocking the action of a certain natural substance in the brain (glutamate) that is believed to be linked to symptoms of Alzheimer’s disease.
How to use Namenda XR
Read the Patient Information Leaflet if available from your pharmacist before you start taking memantine and each time you get a refill. If you have any questions, ask your doctor or pharmacist.
Take this medication by mouth with or without food as directed by your doctor, usually once daily. Swallow the capsules whole. Do not crush or chew the capsules. Doing so can release all of the drugs at once, increasing the risk of side effects. If you have trouble swallowing the capsules whole, the capsule may be opened and the contents may be sprinkled on applesauce. Swallow all of the drug/food mixtures right away without chewing. Do not prepare a supply in advance.
The dosage is based on your medical condition and response to treatment. To reduce your risk of side effects, your doctor may direct you to start this medication at a low dose and gradually increase your dose. Follow your doctor’s instructions carefully.
If switching from another form of memantine to the extended-release form, follow your doctor’s instructions carefully. Do not switch forms of memantine without talking to your doctor first.
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
Tell your doctor right away if you have any serious side effects, including mental/mood changes (such as depression, aggression).
A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
